Food traceability systems allow the consumers or administrative authorities to trace the origins or ingredients of food products. Given the expressed concerns for food safety, the promotion of food traceability systems has occurred in many countries. Although a considerable body of literature has examined the consumer responses in regard to food traceability, relatively little is known about the producers’ adoption behaviors. To fill this knowledge gap, this paper investigates Taiwanese farmers’ participation decision in relation to the Taiwan Agriculture and Food Traceability (TAFT) program; special attention is paid to understanding the roles of the farmers’ program awareness and pesticide residue testing adoption in regard to TAFT participation. Using a national representative sample of the fruit and vegetable farmers in Taiwan, the results indicate that program awareness and pesticide residue testing adoption are the significant determinants of TAFT participation. An awareness of the government’s promotion of the TAFT program and adoption of pesticide residue testing has significantly reduced TAFT non-participation by 28.2% and 21.9% points, respectively.  相似文献

In this study we use detailed daily scanner data on household food purchases to examine monthly food expenditure patterns across food retail channels. We compare food expenditure patterns in high and low-income households comparing those where Supplementary Nutrition Assistance (SNAP) is received in the first 10 days of the month versus households which receive SNAP over the first 15 days of the month. We find that food expenditure patterns vary systematically across the month within different retail channels by income and SNAP payment schedules. Low-income households in early SNAP distribution areas decrease their grocery and mass/club/superstore expenditures at the end of the calendar month and supplement this decrease with increased food expenditures in convenience stores and food away from home. Households in staggered SNAP payment areas show far fewer systematic patterns given the more distributed payment system.  相似文献

Prior work argues that the “market for ideas” supports an open system of innovation, allowing for efficient development of technology across firms. Although this literature has described important features of this market, how it influences the rate and direction of innovation remains an open question. We exploit an exogenous shock to a subset of U.S. medical device firms to study this question. We first document the breakdown in the market for ideas after a federal investigation made it more difficult for the leading orthopedic firms to work with physician‐inventors. We then present evidence of a dramatic decline in the rate of innovation for these firms. Further, a marked shift in direction occurs toward lower‐quality inventions and away from product categories where physician knowledge is critical. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

This paper evaluates the impact of a cassava research-for-development program on farm level outcomes. The program was implemented in the Democratic Republic of Congo from 2001 to 2009. We apply propensity score matching, Rosenbaum bounds on treatment effects, Altonji et al. method of selection on observables and unobservables and endogenous switching regression to farm survey data collected during the 2009 cropping season. We use these methods to test whether the R4D program has a statistically significant effect on outcomes of interest and if these are not driven by selection on unobservables. Using propensity score matching, we find statistically significant positive effects on household participation in cassava markets, adoption of improved varieties and crop management practices and household food adequacy; and no statistically significant effects on yields and profits. The results show that bias due to selection on unobservables is not severe enough to invalidate the impact estimates. Bias may still be a problem that is present in the analysis. But there is evidence that it is not substantial. Although the program does not have a statistically significant positive effect on yields and profits, the significant program effects on market participation, variety adoption, and food adequacy merit further promotion of the program since these positive outcomes tend to be pre-conditions for realizing long-term yield and profit benefits.  相似文献

Does privatization increase plant productivity because the private owner’s objective is different, or because they are better able to control management? And, is privatization sufficient to improve productivity, or is it only effective in combination with competition? We answer these questions using the quasi-experiment of Great Britain’s electricity industry privatization. To separate the effect of a change in objectives from a change in incentives we assume, that the former only affects labor but not fuel productivity. And, assuming that effective competition was only introduced after privatization, we are able to separately identify the effects of privatization and competition. We find that privatization increased labor but not fuel productivity: evidence for the importance of objectives. There is no evidence that the introduction of effective competition after privatization increased labor or fuel productivity: evidence that privatization increases productivity by itself.  相似文献

The paper examines the role and function of public–private interplay in the development of municipal initiatives in the broadband sector. The analysis of initiatives in the Netherlands and Italy shows how the interaction between public and private stakeholders can facilitate local broadband initiatives. This interaction has been vital in aligning the interests of different private and (semi-)public parties, in designing the network and in aggregating sufficient demand for broadband services. The comparative analysis examines the steps involved in these initiatives and the strengths and weaknesses of joint public–private activities. The paper shows that the challenge for cooperating stakeholders has been to foster further investment in the upgrading of the network and in the provision of advanced broadband services.  相似文献

Using the melamine contamination incident in China as an exogenous shock, this paper studies how the investors respond to corporate social responsibilities (CSRs) of listed firms in food industry. We find that investors’ or consumers’ concerns for CSR in the food industry could be significantly influenced by the mounting attention given to CSR-related events. This study offers important policy implications. First, the government, as well as supervisors, should release appropriate policies to improve various firms’ activities on CSR, especially in the food industry. Second, firms, particularly those in the food industry, can obtain long-term benefits by strengthening their CSR-related activities.  相似文献

Using data from the China General Social Survey, the China Family Panel Studies, and a unique dataset of enterprises' online recruitment, this research examines the effect of the digital economy on female employment. The empirical results suggest that the digital economy significantly promotes female employment. Consistent with our theoretical analysis, the estimates indicate that this relationship holds because the digital economy promotes the formation of egalitarian gender perspectives, promotes the use of digital technology, and increases labor demand emphasizing the necessity for female-preference occupations. The dividend of the digital economy is tilted toward vulnerable groups in the labor market, including the low-skilled, older, and rural workforce, and only exerts an employment promotion effect on women without parenting burden. Further examination reveals evidence that digitalization has not led to a holistic improvement in the quality of female employment. Digitalization lengthens the working hours of severely underemployed female workers, and improves women's occupational status and job satisfaction; however, it has a minimal impact on protecting employees' rights and interests or reducing overtime workers' work intensity. Nonself-employed, full-time, and part-time workers all benefit from the development of the digital economy, while self-employed workers do not. In addition, a weakening effect of digitalization on the gender employment gap is not evident, which relates to the digital economy generating a female dividend in terms of promoting gender equality and increasing labor demand but resulting in a digital gender divide in the use of digital technology.  相似文献

The increasing usage of mobile communication and the declining demand for fixed line telephony in Europe make the analysis of substitutional effects between fixed and mobile networks a key aspect for future telecommunication regulation. Using a unique dataset which contains information on all 27 European Union members from 2003 to 2009, we analyze substitutability between fixed and mobile telecommunication services in Europe by applying dynamic panel data techniques. We find strong empirical evidence for substitution from fixed to cellular networks throughout Europe. In addition, the paper reveals resulting policy implications.  相似文献

According to public interest theory, professional licensing solves the lemon problem generated by asymmetric information. In contrast, the capture theory claims that licensing aims at increasing professional salaries by restricting supply. This paper shows that the two theories can be identified using data from one regulated profession and provides an empirical application to the US market for entry level lawyers. The empirical results support capture theory.  相似文献

This paper explores the relationship between research and development (R&D) intensity and circular supply chain management (CSCM) adoption of high-tech manufacturing companies in China to deepen our understanding of how to improve CSCM adoption in emerging economies. In particular, we examine the moderating effect of three kinds of institutional pressures (i.e., regulatory pressure from governmental regulations, mimetic pressure from industry competition, and normative pressure from overseas customer demand) from the perspective of institutional theory. Based on the panel data of 310 Chinese listed companies from 2006 to 2019, we find that R&D intensity positively affects firms’ CSCM adoption. We further observe that this positive effect is strengthened when the ratio of state-owned shares or the degree of industry competition is higher. However, overseas operating income does not affect the impact of R&D intensity on CSCM adoption. Our study contributes to the literature on the innovation – circular economy debate, confirming the positive effect of R&D intensity on firms' CSCM adoption, and provides insights into moderating effects on this relationship in an emerging economy context.  相似文献

Building off the resource‐based view and the knowledge‐based view, our study aims to examine determinants of firms’ R&D outsourcing, using annually‐conducted firm‐level survey data of Japanese R&D companies from 1984–2012. This survey allows us to measure strategic R&D outsourcing, isolated from those more for cost‐reducing, such as prototyping, testing and inspecting. The results corroborate the argument of complementarity in scale between internal R&D and R&D outsourcing. We also find that firms employing more doctorate holders and diversifying in knowledge spaces tend to make more use of R&D outsourcing. This study sheds light on firms’ absorptive capacity, associated both with higher‐order R&D human capital and diversified knowledge spaces, as determinants of R&D outsourcing.  相似文献

In several developing countries in Sub-Saharan Africa, accessibility to digital financial services is increasing because of the development of mobile money services. People previously excluded from the financial system have started to have access to financial services such as receiving and sending remittances, saving, and borrowing. This study examines the effect of network accessibility on the use of mobile money in six developing countries (Bangladesh, Kenya, Nigeria, Pakistan, Tanzania, and Uganda) using GPS information on each household and mobile phone network coverage maps. We find that among these six countries, network accessibility is associated with the use of mobile money in a robust way only in Pakistan and Tanzania. In those two countries, when a household location becomes 10 km closer to the center of the area with multiple mobile networks, the probability of using mobile money increases by 10 percent. In the other countries, we did not find a robust relationship between the use of mobile money and network accessibility. This suggests that increasing network accessibility may not be an efficient method for increasing mobile money adoption in certain countries. The fact that mobile money use rates differ between Tanzania and Pakistan also suggests that the effect of mobile networks is unrelated to the overall level of mobile money adoption.  相似文献

Some recent policy initiatives aimed at preserving the market share of smaller or independent gasoline retailers have either been implemented or proposed in both Canada and the United States. Employing monthly data on average retail prices and market shares across eleven Canadian cities between 1991 and 1997, I find that more aggregate market share in the hands of independent retailers is correlated with higher retail prices, but indirectly associated with lower prices through the corresponding fall in market concentration among vertically integrated firms. The sum of these impacts is negative as indirect effects are larger in magnitude than corresponding direct effects.JEL classification : L1, L4  相似文献

Temporal aggregation is a repeat sale index construction methodology that consists of aggregating paired‐transactions in a moving‐average window. In particular, the methodology is used to calculate the popular S&P/Case‐Shiller home price indices. In this article, I focus the insights of the literature on measurement error to demonstrate that temporal aggregation produces idiosyncratic biases in predictive regression slopes. I further estimate a dynamic instrumental variable (IV) panel for the 20 S&P/Case‐Shiller metro areas. The main empirical finding is that temporal aggregation is a short‐lived statistical disturbance that does not explain the homogenous robust persistence of the indices.  相似文献

Consumers play an integral role in the labor process of app-based food delivery services through their consumption behaviors and performance ratings of workers. Some therefore see them as a potential ally of workers, whereas others view them as beholden by capital. This quantitative study uses power resource theory and a Rasch model to appraise consumers' understandings and attitudes toward working conditions in this segment of the “gig” economy. Drawing on two surveys of 1820 Australian consumers, we find that consumers are a potential yet heterogenous coalitional power resource who may align with workers on certain entitlements like minimum wages.  相似文献

The study explores the role of banks as debt and equity holders for the riskiness of a firm's investment strategy using a panel of Japanese firms in the electronics industry in the period 1992–2004 for the empirical analysis. Based on a conceptual framework grounded in agency and financial intermediation theories, we find that a larger involvement of banks as debt holders in a firm is associated with lower foreign direct investment portfolio risk, while the shareholdings of universal banks increase it, supporting the theoretical predictions.

This article seeks to examine the relationship that exists between the development of high order thinking such as creative and problem solving skills and the need for pupils to achieve high levels of performance in their design and technology public examinations during the final year of compulsory education in the UK.The data under discussion were collected during the final year of a four year research project when a sample of fifty 15–16 year old pupils was chosen from eight schools in the north-east of England.For the purpose of this article a further sub-sample of twenty-seven pupils [twelve pupils who achieved high marks for their project work (sixty-five percent and above) and the fifteen pupils who achieved low marks in their project work (forty percent and below) was selected.In discussing the findings, the relationship between levels of creativity, performance, personal goal characteristics, motivation and design procedures used by the pupils will be highlighted. Conclusions will then be drawn concerning the part played by GCSE Design and Technology examination project work in enhancing the development of creative, innovative thinking and problem solving skills.  相似文献

We study how firms' use of in‐licensing for their initial entry to a business domain can detract from the performance of their subsequent autonomous endeavors in the domain. We argue that in‐licensing produces high levels of causal ambiguity about factors that drive the performance achieved with the licensed product. In turn, the experience that firms gather through pre‐entry licensing is likely to generate superstitious learning and overconfidence that undermine the performance of licensees' subsequent independent operations. The biases will be particularly strong in the face of contextual dissimilarity. We find consistent evidence in a study of firms that entered the global aircraft industry between 1944 and 2000. The research helps advance the understanding of the benefits and costs of markets for technology. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献
